A mold release agent monitoring system includes a molding tool and a supply of mold release agent is provided along with a spray device for applying the mold release agent to the molding tool. A monitoring system monitors an amount of mold release agent applied to the molding tool during a discrete spray cycle. The mold release agent monitoring system provides an output signal to an indicator system for indicating an amount of mold release agent applied during the prior discrete spray cycle. The monitoring system also monitors a total consumption of mold release agent over a determined time period and provides a warning to a consumer of a need to reorder more mold release agent when a remaining mold release agent level falls below a predetermined level.

The present invention relates to a process for preparing hot melt adhesive (HMA), preferably hot melt pressure sensitive adhesive (HMPSA), having a substantially tack-free coating, wherein said HMA, preferably HMPSA, can be easily handled, packed and transported for further use.

The present invention provides a method for producing an antifouling film capable of long-term continuous production of an antifouling film having excellent antifouling properties. The method for producing an antifouling film of the present invention includes Process (1) of applying a resin to a surface of a substrate; Process (2) of applying a second release agent to a surface of a die coated with a first release agent; Process (3) of pushing the substrate to the surface of the die coated with the second release agent with the resin in between to form an uneven structure on a surface of the resin; and Process (4) of curing the resin including the uneven structure on the surface thereof to form a polymer layer. The resin contains an antifouling agent that contains a predetermined compound. The first release agent contains a predetermined compound. The second release agent contains a predetermined compound.

A fabrication process and apparatus for producing three-dimensional objects by depositing a first polymer layer, printing a first ink layer on to the first polymer layer, depositing a second polymer layer on to the first ink layer, and printing a second ink layer on to the second polymer layer. The deposition and printing steps may be repeated until a three-dimensional object is formed. The inks used to form at least one of the first and second ink layers may include dyes or pigments so that the three-dimensional object may be a colored three-dimensional object.

The present invention generally relates to a system and method for using a volatile organic compound (VOC) free low radiant flux LED UV curable composition, and more particularly to unique and novel uses of the composition such as one or two or more of a fire retardant, clear coat, composite material, resin, top coat, improved holdout coating, a sealant coat, and combinations of the same.

Compression molding methods for improving the durability and weatherability of a composite material are provided. The methods include disposing a protective surface film on a composite material; adhering the protective surface film to the composite material; and compression molding the protective surface film. The composite material comprises a thermoplastic polymer and a reinforcement material. The protective surface film comprises at least one stabilizer that minimizes or prevents degradation of the underlying composite material when exposed to ultraviolet radiation and/or heat. The composite material may be heated in an oven having an environment comprising oxygen. The protective surface film may be disposed on the composite material prior to the composite material entering the oven; while the composite material is in the oven; or after the composite material exits the oven.

A synthetic polymer film whose surface has a plurality of raised or recessed portions, wherein a two-dimensional size of the plurality of raised or recessed portions is in a range of not less than 0.5 m and not more than 3 m when viewed in a normal direction of the synthetic polymer film, the synthetic polymer film has a crosslink structure and contains an organic carboxylic acid, at the lapse of 5 minutes since placing a 200 L drop of water on the surface of the synthetic polymer film, a pH of an aqueous solution is less than 4, and an area equivalent circle diameter of the aqueous solution is not less than 20 mm, and at the lapse of 60 seconds since placing a drop of water on the surface of the synthetic polymer film, a static contact angle of the water drop with respect to the surface is less than 3.

The present invention provides a method for producing an antifouling film having excellent antifouling properties and rubbing resistance. The method for producing an antifouling film of the present invention includes Process (1) of applying a resin to a surface of a substrate; Process (2) of pushing the substrate to a die with the resin in between to form an uneven structure on a surface of the resin; and Process (3) of curing the resin including the uneven structure on the surface thereof to form a polymer layer. The resin contains an antifouling agent that contains a compound containing a perfluoro(poly)ether group. The die includes a surface having undergone release treatment using a release agent containing a compound that contains a perfluoro(poly)ether group, a hydrolyzable group, and a Si atom.
