Abstract:
A coating process for producing a selective metallisation comprising the deposition of a metallisation layer, on a motor vehicle lighting device and/or signalling part comprises an application (105 - 107), prior to the metallisation, of a covering film to the parts intended not to be metallised, so as to protect said parts intended not to be metallised during the vacuum metallisation operation (109) and so as to bare said non-metallised parts after removal (110) of said covering film.
Abstract:
The present invention pertains novel composite coating formulation for forming a multilayered film coating on a surface of an article, wherein the coating formulation includes a fluid rubber based coating formulation which, when applied to the article, forms a pliable primary coating, and a polyurethane based coating formulation which, when applied to the article having a cured/dried primary coating on its surface, forms a top coating providing a glossy finish.
Abstract:
Verfahren zum temporären Schützen blanker Oberflächen (11.1) gegen Korrosion und Bauteil mit einer gemäss diesem Verfahren geschützten Oberfläche. In einem ersten Schritt wird eine Korrosionsschutzfolie (12) auf eine zu schützende blanke Oberfläche (11.1) aufgebracht. Dann folgt eine selbstheilende, halbfeste Schutzschicht (13), um die Korrosionsschutzfolie (12) mindestens teilweise abzudecken. Zu einem späteren Zeitpunkt kann mindestens ein Teil der blanken Oberfläche (11.1) durch Abziehen der Korrosionsschutzfolie (12) samt der sich darauf befindenden Schutzschicht (13) freigelegt werden. Die selbstheilende Schutzschicht (13) bildet einen geschlossenen Film und die Korrosionsschutzfolie (12) und/oder die Schutzschicht (13) weisen hydrophob wirkende Bestandteile auf, um zu verhindern, dass Feuchtigkeit zu der zu schützenden blanken Oberfläche (11.1) durchdringt.
Abstract:
A vehicle masking material and method of use. The masking material in one embodiment includes polyvinyl alcohol, ethyl alcohol, glycerine or triethylene glycol, a surfactant, and water. The masking material is applied to a surface which is to be protected from paint overspray or other mechanical process, allowed to dry, and paint is applied. After drying of the paint, the masking material is removed by peeling or water washing.
Abstract:
Methods are provided for protecting exterior surfaces of automobiles and other products, or components of products, against abrasion, abrasive dust, water, acid rain, etc. The methods involve applying to a surface a protective coating composition comprising an emulsion selected from the group consisting of a vinyl-acrylic copolymer emulsion and a vinyl acetate-ethylene emulsion. The emulsion is dried to form a water-resistant protective coating that can be removed from the underlying surface by peeling when no longer desired.
Abstract:
Matière de masquage pour véhicules et procédé d'utilisation de cette matière. La matière de masquage, selon un mode de réalisation, comprend de l'alcool polyvinylique, de l'alcool éthylique, de la glycérine ou du triéthylèneglucol, un agent tensioactif et de l'eau. La matière de masquage est appliquée sur la surface qui doit être protégée contre les projections de peinture ou un autre procédé mécanique, puis on laisse sécher ladite matière et l'on applique la peinture. Lorsque la peinture est sèche, on enlève la matière de masquage par pelage ou par lavage à l'eau.
Abstract:
A strippable, masking film useful in, for example, beautifully finishing a color boundary in two-tone coating of an automobile or the like, and a coating process using it. A coating film containing 1 to 20 parts by weight of carbon black per 100 parts by weight of a resinous component is preferable, with a coating film formed of acrylic emulsion paint and having an adhesion strength of 20 to 1000 g/inch in 180o-peeling strength being particularly preferable. The formed film can be cut by applying a YAG laser equipped with a Q switch oscillation unit in a range of 0.5 to 10 kHz in a repeating frequency of Q switch pulses, and two-tone coating can be beautifully finished utilizing it. When an adhesive paint is used as an underlying layer in contact with a substrate (prime layer) and a flexible, film-forming paint is used as surface layer (upper layer), with each layer containing carbon black described above, better effects can be obtained without damaging a substrate.
Abstract:
A temporary mask composition comprising: (1) a radiation curable monomer including a predominant amount of acrylic and capped prepolymer, (ACRYL)m-X, (2) a radical photoinitiator, (3) an adhesion reducing component selected from the group consisting of: (i) acrylic esters of fatty alcohols (I); (ii) vinyl esters of fatty acids (II) and (iii) monoacrylic esters of polyalkylene oxides (III) where ACRYL= (IV), x = a polymer residue or backbone, m > 2, n > 9, o > 8, p > 3, R = H or alkyl. A method for providing temporary masking of electronic components compatible with a high speed production operation is also disclosed. Suitably the adhesion of the cured composition (22) to the substrate (16) as measured in the tensile shear mode, is between about 5 to 55 psi. This level of adhesion is sufficient to prevent ingress of solvent solder, plating or coating materials but low enough to allow easy dry stripping mechanically or by hand.
