Features & Benefits

Features and Benefits

Crestapol® 1213A is a versatile resin with excellent fire, smoke & toxicity properties and good mechanical properties. Itsviscosity characteristics have been designed to promote a good resin flow through the mold using appropriatereinforcements, whilst minimizing filler settlement during storage. It is recommended for use when excellent low smoke,low toxic fume emissions and fire resistant laminates is desired.

  • Low viscosity
  • Rapid cure
  • Excellent toughness
  • No post cure required
  • Pre-filled with a special grade of Alumina Trihydrate (ATH)
  • Excellent surface finish
  • Excellent FST performance

Applications & Uses

Applications
  • Crestapol® 1213A has been primarily designed for use in closed mold applications, including RTM and Vacuum infusion with suitable reinforcements.
  • Due to its excellent fire, smoke & toxicity properties, the product can be used in the most demanding applications in the building and construction, public transport and railway.
Formulation Guidelines

Crestapo 1213A is a pre-filled, partially accelerated resin and must be thoroughly stirred and allowed to attainworkshop temperature (18°C - 20°C) before use. It requires the addition of a catalyst to start the curing reaction. The recommended catalyst is Dibenzoyl peroxide (50%) and should be added into the resin at a level of 1.0% and thoroughly dispersed.

Technical Details & Test Data

Resin/Glass Ratio

Crestapol® 1213A resin to glass by weight ratio of 3.5 : 1 is recommended for hand lamination.

Additives

Crestapol® 1213A is filled with a special grade of Alumina Trihydrate (ATH) to provide good resin flow in closed moldsystems and also give excellent fire, smoke & toxicity properties. It incorporates anti-settling additives to minimize fillersettlement during storage and promote good filler redispersion in the resin
