BRB Silanil
® 442 provides very good adhesion promotion features between natural minerals and rubber which acts as a coupling agent, bonding between polymer chains and minerals, e.g. clay, mica, silica in order to provide better tensile, tear, modulus strength and better mechanical properties in general. 
BRB Silanil
® 442 having the following benefits:-
• Improved adhesion between mineral fillers and sulfur-cured rubber.
•	Improved process ability during compounding process with good inorganic fillers dispersion and agglomeration reduction.
•	Improved mechanical properties by good coupling performance between inorganic and organic materials. 
•	Improved moisture resistance of rubber compound.
•	Improved abrasion and wear resistance which is durability benefit in shoe soles application.
