Abstract: Additives have been developed that reduce the emission of volatile monomers, e.g. styrene in unsaturated polyester resin system as well as producing a hard, weather resistant gel coat at the surface. Upon reaction, the polymeric additive comes to the surface and reacts with air to form a hard, mar resistance film. The film also has some reactive double bond that will react with the unsaturated polyester portion. The result is a product that has reduced styrene emissions for static or sprayable unsaturated polyester resins, a hard and clean gel coated surface for low pressure architectural sheet application and a class A surface for Sheet Molded and Bulk Molded Parts. These additives exhibit excellent chemical and weathering properties as well as producing a hard mar resistant surface in peroxide or ultra-violet curable polyester systems.

Abstract: Glass clad/polycarbonate structures that can be fabricated to pass stringent impact resistant tests for hurricane resistant window qualifications and/or be used in security application such as bullet resistant side windows in automobiles. The window structure consists of two layers of glass held together with two sided adhesive tape. The function of the tape is to act as a resin diking system and to control the overall thickness of the glass composite. A polycarbonate film between the glass is held in place by a resinous adhesive. The polycarbonate film is smaller in length and width and essentially floats in the cured resin. Expansion and contraction of the polycarbonate film is not restricted in the highly flexible adhesive. Fatigue adhesion failure and subsequent delamination with time is virtually eliminated.The framing structure involves mechanically bonding the frame to the window structure via nylon shims.

Abstract: A fire retardant system useful in a thermosetting resin system comprises a dispersion of particles of a halogen-containing organic material and an inorganic synergist in a liquid phosphorus carrier. The particles in the blend are reduced to 20 microns or less by suitable means, for example, by processing through a 3-roll mill. The composition is incorporated into the resin in an amount of between 3% and 15% by weight of resin where the dispersion remains in suspension during curing of the resin. The thermosetting resin is a saturated or an unsaturated resin such as a polyester, a polyepoxide or a polyurethane. The resin when formed into a ceiling panel has a flame-spread index less than 25 and a smoke rating of 450 or less when tested according to ASTM Test E-84.

Abstract: This invention relates to multiple glass/plastic laminates for ballistic resistant and security applications. The laminates typically comprise a glass lite and a plastic sheet, such as polycarbonate, bonded with an adhesive based on a novel solvent free thermosetting alkyd resin. Subsequent layers can be polycarbonate sheets and/or acrylic sheets and glass lites with the adhesive layer separating the lites and sheets.Further, this invention relates to a vertical liquid pour process which enables the rapid manufacture of bullet resistant glass/plastic laminates without the need for expensive ultra-violet or heat curing ovens. The adhesive cures at temperatures ranging from 60.degree. F. to 90.degree. F. High temperature and high pressure treatments are unnecessary. Laminates produced in this manner with adhesive interlayer will pass all intended ballistic or security tests within a 12 hour period.

This monomer is unique in that it does not etch acrylic or polycarbonate sheets.Further, this invention relates to a vertical liquid pour process which enables the rapid manufacture of bullet resistant glass/plastic laminates without the need for expensive ultra-violet or heat curing ovens.

Abstract: A cationically initiated curable resin system is provided using polyester dicyclopentadiene oligomer blended with monomer having vinyl ether end groups and a cationic initiator. A process for preparing the resin system and a process of coating are also provided.

Abstract: Polyesters containing significant amounts of dicyclopentadiene are produced and used in emulsion form. Superior physical properties, including low linear shrinkage, are obtained.

Abstract: Polyester compositions containing dicyclopentadiene, maleic acid and a compound containing at least one alcoholic hydroxy group, the polyester formed by a two-stage process. In the first stage, maleic acid and dicyclopentadiene are heated to form an intermediate reaction product. In the second stage, the intermediate is heated with a compound containing at least one alcoholic hydroxy group to form the polyester. The compositions containing this polyester and a diluent have good adhesion to metal and plastic substrates, and are useful as automobile body putty primers. These polyester compositions exhibit good adhesion in corrosion-inducing environments, and are useful to protect against further corrosion.
