Unsaturated Polyester

Crystic® ScottBond 117PA has been shown to bond to most materials commonly used in the GRP industry but should be tested prior to use.

Crystic Gelcoat LS 97PA is our best weathering Isophthalic spray gelcoat. It exhibits low colour change and superior gloss retention compared to all other isophthalic competitive gelcoats tested. Can be used across all markets, has excellent water resistance and has Lloyds approval for the marine market.

Crystic® 491PAT is a versatile pre-accelerated unsaturated polyester resin with good water and chemical resistant properties. Crystic® 491PAT was developed for use in a wide range of critical applications which require toughness combined with water and chemical resistance. Crystic® 491PAT is thixotropic and can be applied by either brush or spray equipment and may also be used in the pultrusion process for the production of profile sections.  Crystic® 491PAT is suitable for the fabrication of high performance boat hulls destined for use in warm and tropical waters.

Crystic Glosscoat material hardens rapidly and can be easily sanded to a smooth surface which can be polished to high gloss.

Crystic Gelcoat LS 88PA is our best weathering isophthalic brush gelcoat. It exhibits low colour change and superior gloss retention compared to all other isophthalic competitive gelcoats tested. Can be used in all markets, has excellent water resistance and has Lloyds approval for the marine market.

Crystic 125PA is a quality orthophthalic based unsaturated polyester resin developed specifically for the manufacture of GRP mouldings.

Crystic 125PA is a polyester resin of medium viscosity which meets the requirements of BS3532 : 1990, as a Type “A” resin. It can also be used for flat surface laminations. Laminates made with Crystic 125PA have good mechanical strength, high rigidity and impact resistance, and excellent
dimensional stability. Its curing properties make it especially suitable for fast production processes when used with the recommended curing system.

Crystic Primecoat can be applied wet-on-wet up to a thickness of 1.5mm in one operation without sagging or draining from vertical surfaces. The material hardens rapidly and when cured can be easily sanded to a very smooth finish which can be polished to a surface glossy enough for many applications. Where higher gloss and/or hardness is required it can be surfaced with Crystic Glosscoat.

Crystic Topcoat 508PA White is a pre-accelerated Topcoat with excellent water and weather resistance, designed for use in the marine and building industries. It is based on a high quality isophthalic-NPG polyester resin. It has been formulated for application by brush. It is pigmented using a highly UV resistant grade of titanium dioxide.

NOROX®KP-9 is a methyl ethyl ketone peroxide in phlegmatiser for the curing of unsaturated polyester resins at ambient temperature in combination with cobalt accelerators.

NOROX®MEKP-925H is specifically formulated to reduce gas generation in critical corrosion applications for vinyl ester resins in gel coats, barrier coatings, and corrosion resistant structures. The low hydrogen peroxide level in NOROX®MEKP-925H often requires that the resin promotion system be modified for some resins to obtain reasonable gel times.
