Ambersil RBR100 is a specially formulated release coating for use in a wide variety of rubber moulding applications. When the coating is applied correctly to a pre-heated mould surface to form a thin, inert and thermally stable coating, multiple releases of all natural and synthetic polymers (except silicone elastomers) can be expected.
ADVANTAGES
• Fast curing • Lower mould build-up • Non-flammable
• Easier release • Reduced reject rates
• Maximum multiple release
• Releases all rubber compounds except silicone elastomers
MOULD PREPARATION
New Moulds: Mould surfaces must be thoroughly cleaned and dried.
All traces of previous release agents and moulding
residues must be cleaned away. Ambersil Polyester
Mould Cleaner is recommended for cleaning away these
release agent residues.
Old Moulds: Some form of abrasion will probably be required (eg.
grit, sand or glass beading) followed by a solvent wash
with Ambersil Polyester Mould Cleaner.
APPLICATION
Ambersil RBR100 can be applied by any of the following methods.
• Conventional Air Spray • HVLP Spray • Airless Spray
Ambersil RBR100 is suitable for application directly onto heated moulds at temperatures up to 204°C (400°F) and moulds preheated to a minimum of 60°C (140°F).
Using a finely atomised spray pattern. Ambersil RBR100 should be applied at a distance of 8-12” from the mould surface. Cure times can be calculated from the graph below. See (Figure 1 overleaf).
For hot (120-200°C) moulds, new or porous moulds apply a minimum of 6 coats for warm (60-120°C) moulds a minimum of 4 coats should be applied with special attention paid to avoiding emulsion accumulation and run marks due to over application.
Allow sufficient time for RBR100 to cure prior to production.
