CASTALDO LONG-LIFE LIQUACAST JEWELRY MOLDING RUBBER LONG LIFE LIQUID 0% Shrinkage RTV Liquid Jewelry Molding Rubber Will Not Soften with Age Ordinary low-cost RTV liquid rubber molds become soft and unusable over time, wasting the time, effort and skill invested in making them. Sometimes they even turn back into liquid rubber! LiquaCast® Long-Life™ 0% shrinkage RTV rubber is formulated to last for decades without softening, distorting or degrading in any way. Have you looked at your library of rubber molds recently? If you have made low-cost RTV liquid rubber molds in the past many of them are probably becoming useless due to age, sometimes even after only 2 years. Years of work could be slowly melting. Wouldn’t you rather have molds that last and last? Extremely Strong and Firmer LiquaCast Long-Life makes molds that are extremely strong, tough and tear-resistant, another reason they will last and last despiterepeateduse. It’s perfect for complex molds, difficult undercuts and spirals and cores. And it’s compatible with mostcomputer-generated CAD-CAM resin and difficult to mold CAD-CAM wax patterns. Much Easier to Use LiquaCast Long-Life is easy to use, too. Low viscosity means that it is easy to measure, easy to mix, easy to vacuum and easy to pour. And it’s easy 1:1 mix ratio by either weight or volume means that measuring and mixing mistakes are much less likely than with 1:10 compounds. LiquaCast Long-Life 0% shrinkage liquid RTV is a firmer rubber - ideal for delicate & difficult to inject patterns. Firmer rubber means less pattern distortion during injection. Small channels will not be squeezed closed during injection and result in patterns that are not filled completely. Great for filigree! Makes More Molds LiquaCast Long-Life costs a little more than other low-cost RTV rubbers, but produces up to 40% more moldsper pound or kilogram. Price per mold is more important than price per pound or kilogram. Long-Life compares favorably in price with other low-cost liquid RTV rubbers. Molds made with LiquaCast Long-Life have a glossy, shiny surface that produce waxes with a glossy, shiny s urface. That means greater efficiency because the final castings require less polishing and generate less metal loss.
