REVERSOL P-92

formulated from a neopentyl glycol / isophthalic base resin. It is formulated for brush application and can be pigmented with most of the unsaturated polyester based pigment pastes. It is resilient and heat resistant, and can be polished to a high gloss. For mould construction, Reversol P-92 should be controlled at 0.8 – 1.2mm wet film thickness. As a guide, approximately 600 – 800g/m2 of gelcoat mixture (depending on pigment) will give the required thickness when evenly applied. Stirring should be done by hand, or with a low shear mixer to avoid aeration. It should be allowed to stand to regain thixotropy before using. Methyl Ethyl Ketone Peroxide (MEKP), for example Butanox M-50, at 1-2% dosage is recommended for used in tropical condition. In order to obtain optimum life span of mould constructed using Reversol P-92, it is recommended to do post curing at 50ºC for 30 hours or at ambient condition for 1 - 2 weeks before putting the mould into use.

Application Advice/Typical Applications

(# Curing schedule was 12 hours at 25ºC followed by 12hr at 50ºC 3 hours at 80ºC except for Deflection Temperature where schedule was 12 hours 25ºC followed by 12hr at 50ºC, 3 hours 80ºC and 3 hours at 120ºC)

FRP composite mould

Shipping and Storage

To ensure maximum stability and maintain optimum resin properties, Reversol P-92 should be stored in close containers maintained below 32ºC and away from heat sources and sunlight. All storage should conform to local fire and building codes. Drums should be stored away from all sources of flame or combustion. Inventory should be maintained at minimum reasonable stock level on first-in-first-out basis. When properly stored, Reversol P-92 will remain stable for 3 months from date of delivery.
