Manufacturers of high-performance paint & coating formulations, as well as related applications like adhesives, inks, and sealants, incorporate organofunctional silanes to achieve key performance enhancements. To support the formulator in these applications, Gantrade offers an array of silanes applicable to both water-based and solvent-based systems.
Gantrade offers an array of organofunctional silanes for application in diverse settings, from the oilfield to paint & coatings. These organofunctional silanes are extremely versatile reactive intermediates, widely employed in coatings, adhesives, sealants & elastomers (CASE), inks, and related applications.
Some of the most common applications for organofunctional silanes include the following:
In polyurethane processing, manufacturers always use polyester polyols as important raw materials, to make prepolymers with isocyanates or as chain extenders or curatives. Due to the good oxidation and UV resistance, good wear and tear resistance, good heat performance and solvent resistance. Many polyurethane parts feature polyester polyols to prepare them for the toughest environments and applications.
Aqueous acrylic polymer emulsions are replacing solvent-based polymer systems thanks to environmental regulations limiting volatile organic compounds (VOCs) and major improvements in the performance characteristics of the emulsion-based products.
Polycaprolactone polyols are considered a special class of aliphatic polyester polyols, used as the soft block segment of high-performance polyurethane elastomers. The polycaprolactone polyols can be produced with very low acid values; perfect end-termination functionality; and narrow molecular weight distributions (MWD). These features manifest themselves in polyurethanes characterized by the following property profile, many of which are best-in-class performance attributes.
Methyl methacrylate (MMA) is a monomer that’s also known as methacrylic acid, methyl ester.
1,4-butanediol (BDO/1,4-BD) is a versatile liquid diol intermediate with reactive primary hydroxyl functionality and a linear structure that lends itself to formulating polyurethanes with a good balance of hardness and low temperature flexibility; high strength and durability; and thermal stability.
Polyurea is formed by reaction of diisocyanates and diamines, and it is one of the toughest synthetic polymer materials. These are some of its attributes:
Glacial Acrylic Acid Monomer (GAA) is an unsaturated carboxylic acid co-monomer used as a building block to produced acid functional and crosslinked acrylic copolymers and polyacrylic acids. GAA readily copolymerizes with acrylic and methacrylic esters, ethylene, vinyl acetate, styrene, butadiene, acrylonitrile, maleic esters, vinyl chloride and vinylidene chloride. Copolymers which contain GAA can be solubilized or exhibit improved dispersions in water; the carboxylic acid moiety can be used for coupling or crosslinking reactions, and improved adhesion. GAA copolymers are used in the form of their free acid, ammonium salts or alkali salts. These polymeric uses for GAA account for approximately 45 % of the consumption of acrylic acid monomer (the manufacture of acrylate esters is the other major use).
