Product Highlights

• Formulated without protic and nonprotic solvents
• Soluble in water
• Does not contribute to color when aged in resin formulations
• N-H reactivity without the strong basic characteristics of aminosilanes
• Longer pot life than aminosilane in reactive phenolic, epoxy, urea-melamine or polyurethane resin formulations

Recommeded Usage

• Coupling agent for insulation phenolic wool binders and glass fiber sizes used to reinforce nylon resins
• Finish for woven glass fiber fabrics
• Treatment for particulate fillers used to reinforce nylon, phenolic or epoxy resin
• Additive for foundry sand and abrasive grinding wheel binders
• Adhesion promoter in urethane-based coatings, sealants and caulks
• Component in primers

Instruction for Use

Silquest A-1524 silane use level is dependent upon the surface area of the particulate filler or glass fiber reinforcement. Typical starting concentrations may range from 0.5 to 1 weight percent, based upon the weight and type of reinforcement used. Sand and other low surface area fillers or substrates may require less than 0.1 weight percent silane.

When Silquest A-1524 silane is added to a resin formulation, the use level is typically in the range of 0.5 to 1 weight percent, based on the weight of the resin. Silquest A-1524 silane is soluble in methanol, ethanol, acetone, toluene and water. The silane hydrolyses in water and releases methanol.

The hydrolysis product of Silquest A-1524 silane, gamma-ureidopropylsilanetriol, is stable at one weight percent in water at pH of 4 for greater than 72 hours.

Silquest A-1524 silane should be protected from low temperatures as it freezes at less than 5 °C. While freezing does not harm Silquest A-1524 silane, should it occur, the material should be well stirred after thawing to ensure uniform concentration.
