The proper procedure requires that the nonporous fixture be sand blasted to create a rough surface for the epoxy primer to adhere to. Once the primer has dried the topcoat is applied. Since a true epoxy begins to yellow at the age of 1 year acrylic polyurethane compound is used in the topcoat. This resin is also catalyzed with a hardener and ...
They require a dry, clean surface during application to gain adhesion. Topical sealers may alter the coefficient of friction which can make substrates slick when wet – a condition that can be remedied by adding anti-skid materials. Life span is generally 1-5 years, although high-end epoxy/urethane systems can last significantly longer.
The second most important part of FBE coatings is the curing agent or hardener. Curing agents react either with the epoxy ring or with the hydroxyl groups, along the epoxy molecular chain. Various types of curing agents, used in FBE manufacture, include dicyandiamide, aromatic amines, aliphatic diamines and organic acid anhydrides. [6]
Difunctional versions tend to give flexibility and thus toughness to epoxy resin systems. [4] [5] [6] Studies have been done on the cured properties of epoxy systems using different functionality polyetheramines. [7] As epoxy curatives, they may then be further formulated into CASE applications: coatings, adhesives, sealants, and elastomers.
Sealant is a substance used to block the passage of fluids through openings in materials, [1] a type of mechanical seal. In building construction sealant is sometimes synonymous with caulk (especially if acrylic latex or polyurethane based) [2] and also serve the purposes of blocking dust, sound and heat transmission. Sealants may be weak or ...
Some primers can be tinted to match more closely with the color of the finishing paint. If the finishing paint is a deep color, tinting the primer can reduce the number of layers of finishing paint that are necessary for good uniformity across the painted surface. Primers are also used to hide joints and seams to give a finished look.
