Reversol P-780 PLT is an orthophthalic, flexible, promoted, clear color gelcoat designed for spray application. For normal moulding application, Reversol P- 780 PLT should be controlled to 0.8 – 1.0 mm wet film thickness. Medium reactivity Methyl Ethyl Ketone Peroxide catalyst (MEKP), for example Butanox M-50, at 1 – 2% dosage is recommended for use in tropical condition. Reversol P-780 PLT gelcoat should not be apply at below 15ºC condition. Always homogenize this gelcoat before adding MEKP, by stirring well with hand or with a low shear mixer to avoid aeration, and then allow to stand to regain thixotropy. It is not advisable to add filler into gelcoat because it can adversely affect the properties of gelcoat. Post Curing of GRP articles coated with this gelcoat is recommended before putting these articles into service.
