Offering fast cure at low to moderate temperatures, platinum catalysts have the added ability to maximize bath life within defined temperature ranges.

Advantages

• Yields faster
• More complete cure at low temperatures
• Less prone to silicon migration
• Non-reversible, non-blocking
• Does not require post cure, making two-sided differential release and in-line applications possible
• More durable coating with more stable and predictable release
• More avenues for controlling performance

Disadvantages

• Susceptibility to catalyst poisoning by:
  • Amines
  • Sulphides
  • Phosphides
  • Organotin salts
• Potential for interaction with acrylics

Advantages

• Does not interact with most adhesives.
• Excellent acrylic stability
• Relatively difficult to poison

Disadvantages

• Less sensitive to substrate inhibition in comparison to platinum-catalyzed coatings
• Cures more slowly and requires a higher 
  temperature
• Not suited for temperature sensitive substrates 
• Not suited for food contact applications

Catalyzed by tin, condensation cure chemistry is a cost-effective solution that maintains versatility and stability. 

Advantages

• Coating is robust and resistant to substrate inhibition and catalyst poisoning
• Minimal adhesive interaction

Disadvantages

• Necessity for post-cure often rules out two-sided and in-line applications
• Blocking may occur
• Greater potential for silicone migration
• Tin and rubber are mildly interactive - tin catalyzed coatings are less desirable with SBR adhesives
