Scott Bader to Present Crestabond® Methacrylate Structural Adhesives at 17th China Composites Show

Published on 2011-09-09. Author : SpecialChem

At the 17th China Composites Show in Shanghai Scott Bader Asia Pacific is exhibiting their range of Crystic® high performance specialty resins, gelcoats and adhesives. Scott Bader has on its stand (A 614/616) the new Crystic Permabright spray and brush marine gelcoat along with other innovative new products in their specialty products range: primerless Crestabond® methacrylate structural adhesives; new closed mould and pultrusion Crestapol® resins; plus low smoke fire retardant (FR) gelcoats and resin laminate systems with test approvals for a variety of building and land transportation applications from Epiradeatuer NFP/ NFF, DIN; ASTM and CEN TS 45545-2 (Firestarr HL2) standards. The Crestapol range now includes the latest addition to the range, Crestapol 1250LV, which has been specially developed for both glass and carbon fiber lamination. Vacuum infusion demonstrations are also be taking place during the show on the Composites One stand (No. 513) using Crestapol 1212 resin.

Crestapol 1250LV is an ambient curing urethane acrylate thermosetting resin. It has been developed for producing high performance carbon fibre reinforced and glass fibre (GRP) parts by vacuum infusion or resin transfer moulding (RTM). It has processing flexibility to suit different production conditions and requirements. Crestapol 1250LV provides a cost effective alternative to epoxy infusion resin systems, with competitive strength properties and an excellent surface finish with minimal print through. A part made from carbon fiber reinforced Crestapol 1250LV is on the stand.

Crystic Permabright is Scott Bader's new D-Iso/NPG marine grade gelcoat, which is claimed sets a new standard for long term UV weathering performance by providing significantly improved long term colour stability; the Florida test results obtained clearly show that Crystic Permabright gelcoat is able to provide two times better colour stability than the next best in class Iso/NPG and four times better than a standard isophthalic gelcoat.

Additionally, Scott Bader is featuring their range of primerless Crestabond methacrylate structural adhesives for bonding a wide variety of composite, metal and plastic substrates; none or only minimal surface cleaning of a substrate is required. Crestabond adhesives have been successfully used in a variety of marine and transportation GRP applications.

During the show in the technical forum, two papers are also to be presented by technical representatives from Scott Bader: one paper covers their Crestabond range of structural adhesives, based on their innovative methacrylate chemistry; the other technical paper covers the performance and use of Crestapol resins as part of a fire retardant laminate system, as they can be heavily filled to achieve meet a variety of smoke and fire test standards.
