Definitions
- the present invention relates to improved resins for use in gel coat compositions.
- the gel coat composition is spread across the sur- face of the mold by any one of a number of conventional techniques, e .. g., brushing, hand lay-up, or spraying, and usually as a relatively thick layer, e.g., 0.5 to 0.8 mm, to maximize its weather and wear resistance, and if the molded article is fiber- reinforced, to help mask the fiber reinforcement pattern which can show through the gel coat due to inherent resin shrinkage that occurs around the fibers during cure.
- a gel coat is a prepromoted resin, typ- ically a polyester, and typically is pigmented.
- the gel coat After the gel coat is applied to the surface of the mold, it is at least partially cured.
- the cure can be promoted through the use of free radical polymerization processes .
- the gel coat In addition to imparting weather and wear resistance to the molded article, the gel coat also imparts cosmetic properties to the article. In many applications, particularly consumer applications such as automobile parts, shower stalls, bathtub enclosures, and appliances, a high initial gloss and extended gloss retention are very desirable or necessary properties for the molded article.
- unsaturated polyesters in admixture with unsaturated aromatic monomers, such as styrene, in gel coat compositions is well known in the art.
- the unsaturated polyesters are prepared from the condensation of unsaturated acids or acid anhydrides with polyols.
- a common unsaturated acid is either maleic anhydride or fumaric acid. While not intending to be bound by theory, it is believed that ester linkages formed from these ingredients exhibit poor hydrolysis resistance, and consequently the overall film performance of a coating film based on these polymers is relatively poor.
- Aromatic di- acids such as isophthalic acid, have been used to help improve the hydrolysis resistance of the film. However, the presence of aromatic nuclei reduces the exterior durability of the coating film.
- One high quality gel coat is an isophthalic acid/neopentyl glycol (IPA/NPG) -based unsaturated polyester diluted in styrene monomer.
- IPA/NPG isophthalic acid/neopentyl glycol
- the cured gel coats are rather soft materials of overall low chemical resistance and limited outdoor durability. • The art has a need for a more durable gel coat because IPA/NPG gel coats can fade and chalk, even before the molded plastic article is sold.
- Other gel coats currently in use include epoxy, urethane, and vinyl ester resins, particularly when greater flexibility and water resistance are desired. However, these materials also tend to fade and lose their gloss quickly, usually require higher curing temperatures, and are much more difficult to use than the commonly available unsaturated polyester products.
- these resins are difficult to formulate into gel coat compositions having desirable physical properties, in-mold curing times, and handling properties without the use of more than a nominal amount of styrene or similar volatile monomer as a reactive diluent.
- these diluents are the subject of numerous federal, state, and local regulations, manufacturers of molded plastic articles prefer to use gel coat compositions that contain minimal styrene or similar volatile monomers.
- vinyl esters formed from the reaction of an aromatic polyepoxide with an unsaturated monocarboxylic acid have excellent hydrolysis resistance.
- the presence of aromatic nuclei and the necessary addition of high levels of unsaturated aromatic monomers to obtain a sprayable viscosity leads to unacceptable exterior durability.
- Vinyl ester resins based on aliphatic polyepoxides exhibit poor hydrolysis resistance.
- Present-day gel coat compositions fail to meet the requirements for weatherability, color stability, and hydrolysis resistance for external applications, such as automotive applications. These requirements include no significant loss of gloss, change in color, or build-up of chalky oxidation products on the surface of the cured gel coat. While not intending to be bound by theory, present-day gel coat compositions fail because of the chemistry used in preparing the base resin incorporated into the gel coat composition. Typically, the chemistry is based on an unsaturated poly- ester, or a hybrid chemistry based on polyesters and acrylates . The present invention is directed to a new resin for use in a gel coat composition that overcomes problems and disadvantages associated with prior base resins used in gel coat compositions.
- the present invention is directed to a urethane acrylate resin that exhibits substantially improved performance over present-day base resins used in gel coat compositions.
- Gel coat compositions containing a present urethane acrylate resin retain a high gloss and consistent color over extended time periods .
- the above-described deficiencies in prior gel coat compositions have been overcome by incor- porating a urethane acrylate resin of the present invention into a gel coat composition.

- one important aspect of the present invention is to provide a urethane acrylate gel coat resin containing a reaction product of com- ponent A (oligoester) , component B (diisocyanate) , and component C (hydroxyalkyl (meth) acrylate) , and having an idealized structure (I) :
- reaction product of components A, B, and C also contains other species in addition to idealized structure (I) and this invention is not limited to idealized structure (I) .
- Another aspect of the present invention is to provide a urethane acrylate gel coat resin for incorporation into a gel coat composition.
- the gel coat composition provides a cured gel coat having improved weatherability, including gloss retention and color stability.
- Still another aspect of the present inven- tion is to provide a urethane acrylate gel coat resin having terminal acrylate groups.
- the terminal acrylate groups can be polymerized, for- example, using free radical polymerization techniques to provide a cured gel coat .
