RTV 664 AB
Master Molder RTV600 series is comprised of RTV662, RTV664, and RTV668. Each is a two part, addition (platinum) curing mold making product offering high durometer for applications requiring greater dimensional stability.
模具用膠RTV600系列包括RTV662,RTV664和RTV668。均為雙組份構(gòu)成,應(yīng)用于對(duì)硬度和穩(wěn)定性都有極高要求的模具生產(chǎn)。
RTV662 offers the highest durometer (68 Shore A) in the series, as well as the longest worklife. It is ideally suited for embossing, release rolls, and large molds.
RTV664 is a high durometer (62 Shore A), long work life product. It offers excellent chemical and abrasion resistance and was designed for high production on manufacturing lines.
RTV664是一種硬度高(62 Shore A),壽命長(zhǎng)的產(chǎn)品,具有極好的抗化學(xué)反應(yīng)和抗磨損能力,適用于生產(chǎn)量大的生產(chǎn)線
RTV668 is a high durometer (62 Shore A) product formulated for sulfur resistance. It is ideal for casting with masters made of pine, oak, and elm.
