Specialized adhesive formulations have been developed that are characterized by outstanding abrasion resistance. Abrasion resistance refers to the ability of an adhesive to resist wearing due to contact with another surface. Wearing occurs when a hard rough surface slides across a softer surface, usually the adhesive material, causing the undesired removal of material from the surface.
Classification of Surface Abrasion
Surface abrasion may be classified in three different ways: wear, scuffing and fatigue. These actions include the deterioration of material from a solid surface by the recurrent movement of another surface, the scraping of a surface and the stressing of an adhesive material repeatedly.
When countering these stresses, adhesive performance depends on the intrinsic formulation properties of the adhesive system, the localized film thickness of the adhesive, as well as the adhesion properties of the system to the specific substrate.
Standard Test Method for Abrasion Resistance of Organic Coatings by the Taber Abraser
Master Bond sent out various samples for independent testing according to the "Abrasion Resistance of Organic Coatings by the Taber Abraser, ASTM D4060-14." The results are indicated in the table below:
|Abrasion resistance, CS-17 wheel, 1,000 cycles||Loss in weight, test method ASTM D4060-14|
Common Applications for Master Bond Abrasive Resistant Adhesives
From road materials to soil/sand to pigments to metal powders to quartz to ceramics our abrasion resistant polymers are designed to meet demanding requirements. Typical applications are:
- Butterfly valves
- Heat exchangers
- Handling equipment
- Slurry lines
- Vibrating screens
- Downhole tools
- Hydraulic systems
High wear resistant Master Bond epoxy, polyurethane compounds extend the service life of valuable industrial equipment/components by ensuring the structural integrity of the mated substrates. They possess superior mechanical strength properties and can withstand exposure to fine, coarse, large particle abrasion, chemical attack from oils, hydraulic fluids, acids, bases, severe impact, corrosion and heat aging. Solvent free products containing silicon/silicon carbide aggregates can be dispensed manually/automatically, uniformly in a variety of thicknesses for different sized/shaped parts. Common manual application techniques include using brushing, trowels, spatula, roller coating, double barrel cartridges in a gun applicator. Non-drip pastes will not sag even when applied on vertical surfaces and have excellent gap filling capability.
Master Bond wear resistant adhesive systems adhere well to properly prepared nonmetallic and metallic substrates such as aluminum, carbon steel, stainless steel, cast iron, bronze, copper, brass. Custom products feature superior compressive strength, guard against liquid immersion and vapors from aggressive chemicals, cure quickly at ambient temperatures to speed productivity, have low thermal expansion coefficients. Most importantly the reliability/efficiency of machine/equipment operations are greatly enhanced avoiding costly downtime and improving customer satisfaction/loyalty for manufacturing companies.
