What to do when silicone rubber remains sticky



ltsection class="guide-section">

Removing Sticky Silicone Rubber

When silicone rubber remains sticky after curing, it is important to act promptly. This could be due to an error in the mixing ratio or unfavorable environmental conditions. To remove the sticky part, a specific solvent can be used, allowing it to act for a few minutes. Subsequently, the softened material is removed with a cloth or plastic scraper. This procedure is also useful for cleaning molds or surfaces compromised by incompletely cured residues.

Preventing Stickiness Effect

To avoid stickiness issues, it is essential to store the rubber in a cool, dry place away from heat sources. The container must always be well sealed to prevent contamination or catalyst evaporation. Excessive humidity or low temperatures can also compromise the chemical reaction. Working in controlled environments around 20-25°C ensures stable and uniform curing. Proper material storage ensures reliable and long-lasting results over time.

Using Anti-Stick Agents

To improve detachment and prevent silicone rubber adhesion, specific anti-stick agents can be used. These products, often in spray form, create a thin film that facilitates the separation of the rubber from the mold. They should be applied carefully before casting, avoiding excess. There are versions compatible with food-safe or professional use depending on the application. On the website www.resinpro.it, various types of mold release agents suitable for every need can be found.

Practical Tips for Effective Management

To work properly with silicone rubber, it is essential to use clean and dry tools. Even small traces of dust or residues can alter the curing process. The recommended base-catalyst ratio must be respected, and thorough mixing for at least two minutes is necessary. Slow pouring is helpful to avoid bubbles and achieve smooth surfaces. The website www.resinpro.it offers tutorials and guides that explain each phase of the process clearly.
