Adhesives, Sealants & Lubricants

Adhesives, sealants and lubricants serve different purposes, even when they appear in the same work area. Adhesives join materials, sealants close gaps and protect against moisture or contaminants, while lubricants reduce friction and wear. The right choice depends on the materials involved, the environment and whether the connection must be permanent, flexible, removable or easy to service.

How to choose the right product

Start with the job rather than the product name. Identify whether the product needs to bond two surfaces, fill a joint, create a protective barrier or lubricate moving parts. Then consider the following:

• Materials: Check whether the formula is suitable for metals, plastics, rubber, glass, wood, painted surfaces or composites. Some materials require a primer or special surface preparation.
• Working conditions: Account for heat, moisture, chemicals, vibration, outdoor exposure and load. A product suited to a dry indoor repair may not be appropriate for continuous industrial exposure.
• Application method: Compare tubes, cartridges, bottles, rolls, sprays and other formats. The container and dispensing method affect precision, coverage and cleanup.
• Cure and set behavior: Look for working time, handling time and full-cure guidance. Fast-setting products can be useful for small repairs, while longer working time helps with alignment and larger assemblies.
• Finished properties: Compare flexibility, hardness, gap-filling ability, bond strength, clarity and resistance to water or chemicals when those characteristics matter.

Explore adhesive and sealant types

The catalog’s larger subcategories include several common formats and specialized options:

• Adhesive Tapes are convenient for mounting, joining, masking or bundling without liquid application. Compare backing material, adhesive type, thickness, width and removal characteristics.
• Cyanoacrylate Adhesives are often selected for quick bonding of compatible, closely fitting surfaces. Pay attention to viscosity, gap-filling capability and material compatibility.
• Caulk is used to fill joints and gaps, commonly where movement, moisture or an air seal must be considered. Compare flexibility, paintability, application area and curing requirements.
• Epoxy Adhesives are two-part systems that can suit demanding repairs and assembly work. Check mix ratio, pot life, cure time, strength and resistance specifications.
• Contact Cements are designed for bonding surfaces after application and appropriate setup. Review open time, substrate compatibility, ventilation guidance and cleanup requirements.
• Industrial Sealants focus on sealing and protecting joints, seams or components. Compare elasticity, temperature range, chemical resistance and adhesion to the intended substrates.
• Silicone Adhesives can be useful where flexibility and environmental resistance are important. Check cure chemistry, adhesion, movement capability and whether the cured product is suitable for the application.
• Industrial Adhesives cover bonding solutions for assembly, manufacturing and repair. Compare dispensing format, cure method, production requirements and compatible materials.

For maintenance rather than bonding, Industrial Lubricants can be compared by viscosity, operating temperature, application method and compatibility with seals, plastics or metals. Coatings may be more suitable when the goal is to protect or cover a surface instead of joining components.

Specifications that deserve close attention

A product’s stated strength alone does not determine whether it fits the job. For adhesives, compare tensile or shear performance where provided, along with bond-line requirements, surface preparation and resistance to impact or vibration. For sealants, look at movement capability, shrinkage, adhesion and the way the cured bead behaves over time.

Packaging also matters. A precision tip may help with small repairs, while a cartridge may be better for repeated seams or larger areas. Two-part formulas may require a mixer, applicator or accurate ratio. Tapes should be assessed for clean removal, conformability and performance on the actual surface.

For lubricants, compare the lubricant type, viscosity grade, temperature limits and whether the product is intended for a specific machine, bearing, chain, gear or other component. Always follow the equipment manufacturer’s maintenance guidance when available.

Brands represented in the catalog

Brands well represented in this category include Loctite, Gorilla, スリーエム(3M), DAP, Command, Scotch, Duck, VELCRO Brand, J-B Weld, Red Devil, XFasten and MITREAPEL. Brand familiarity can help narrow a search, but the technical specifications and intended application should remain the deciding factors. Products from the same brand may be designed for very different surfaces, cure methods and environments.

Safe use and surface preparation

Clean, dry and properly prepared surfaces usually provide a more reliable starting point. Remove dust, oil, rust or loose material as appropriate, and follow the product’s instructions for roughening, priming or masking. Test an inconspicuous area when staining, discoloration or surface damage is possible.

Use suitable ventilation and personal protective equipment for the formula and task. Keep uncured products away from skin and eyes, observe flammability guidance, and allow the recommended cure period before loading a joint or exposing it to service conditions. Store opened containers as directed to limit premature curing or contamination.

If the project also involves hardware or component installation, browse Fasteners alongside this category. For measurement and verification tasks, Test, Measure & Inspect may help identify the tools needed to check fit, alignment or performance.

Frequently asked questions

What is the difference between an adhesive and a sealant?

An adhesive is primarily intended to join surfaces. A sealant is intended to close gaps or joints and help block moisture, air, dust or other contaminants, although some products can perform both functions.

When should epoxy be considered instead of cyanoacrylate?

Epoxy may be preferable when gap filling, a more substantial bond line or greater resistance to impact and environmental exposure is needed. Cyanoacrylate can suit quick bonding of closely fitting compatible surfaces.

How should adhesive surfaces be prepared?

Follow the product instructions. Preparation may include cleaning, drying, degreasing, light abrasion or primer application. Avoid bonding over loose coatings or contamination unless the product specifically allows it.

How do I choose between liquid adhesive and adhesive tape?

Choose tape for clean, quick application, consistent coverage or situations where liquid curing is inconvenient. Choose liquid adhesive when you need to fill an irregular joint, create a stronger bond line or reach a complex surface.

What should be checked before using an industrial lubricant?

Check the equipment requirements, viscosity, operating temperature, load, application method and compatibility with seals, plastics and other nearby materials. Do not mix products unless the manufacturer permits it.
