Product Description

Introduction
Crystic 491 and 491PA are thixotropic, isophthalic polyester resins with good water and chemical resistant properties.

Applications
Crystic 491 and 491PA were developed for use in a wide range of critical applications which require toughness combined with water and chemical resistance.
They are versatile resins suitable for the fabrication of high performance boat hulls destined for use in warm or tropical areas, and form a matched performance system when used with Crystic Gelcoat 65PA.
They are also suitable for the manufacture of chemical plant, tanks, pipes and chemical containers.
Crystic 491PA can be brush or spray applied, and may also be used in the pultrusion process.

Features and Benefits
Crystic 491 and 491PA have a low level of residual styrene which enables the production of non-toxic, non-tainting laminated.
This makes then especially suitable for the manufacture of vessels to contain food and potable liquids including drinking water, milk wines and spirits.

Approvals

Crystic 491PA is approved by Lloyd’s Register of Shipping for use in the construction of craft under their survey.
In conjunction with Crystic Gelcoat 65PA, Crystic 491PA is approved under the Water Regulations Advisory Scheme (WRAS) for use in contact with potable water.

Product Characteristics

Formulation

Should be allowed to attain workshop temperature (18°C – 20°C) before use.
Crystic 491PA needs only the addition of catalyst to start the curing reaction.
For general mouldings, the recommended catalyst is Catalyst M (orButanox M50) but for applications involving foodstuffs and potable liquids, the recommended catalyst is Catalyst O (or
Interox LA3).

The catalyst should be added at 2% into the resin and thoroughly dispersed shortly before use.
