Silicone Curing Inhibitor,Platinum Catalyst Retarder
Overview
Our silicone inhibitor is a high-purity retarder specially developed for platinum-based addition cure silicone systems. It can effectively restrain the crosslinking reaction between vinyl silicone and hydrogen silicone oil at room temperature, avoid premature gelation during production, and completely lose inhibition activity under medium-high temperature heating to realize full vulcanization of silicone without damaging the physical and optical performance of silicone finished goods. This product is widely adopted by silicone factories, coating manufacturers and electronic material suppliers worldwide.
Technical Specifications
- Appearance: Colorless transparent liquid
- Viscosity (25℃): 5–50 mPa·s
- Active ingredient: ≥99%
- Density: 0.82–0.95 g/cm³
- Flash point: Over 90℃
- Suggested addition ratio: 0.01% to 0.5% of total silicone mass
- Shelf life (original sealed package): 12 months under 25℃ cool and dry storage
- Mixing storage life: 3–30 days after blending with silicone base (adjustable by dosage)
Core Characteristics
- Powerful retardation performance for platinum catalyzed silicone addition reaction
- Perfect miscibility with vinyl silicone oil, liquid silicone rubber and hydrogen-containing silicone oil
- No precipitation, no haze, no yellowing after high-temperature vulcanization
- Low addition amount brings obvious anti-gelling effect
- Non-toxic, low-odor, halogen-free, RoHS & food contact safe
- Stable inhibition effect, consistent batch performance
- Rapidly deactivate inhibition under heating to ensure complete silicone curing
Product Superiorities
- Cut production waste: Eliminate loss of silicone raw materials caused by fast spontaneous curing during mixing, transfer and molding.
- Flexible production schedule: Extend working time of mixed silicone slurry, support large-batch continuous production.
- Preserve silicone product quality: No deterioration on hardness, elasticity, tensile strength, transparency and adhesion after curing.
- Wide industry adaptability: Matches all mainstream two-component addition silicone systems.
- Simple operation: Direct stirring mixing, no extra solvent or complex pre-treatment required.
- High environmental standard: Safe for food contact, medical devices and consumer electronics manufacturing.
Main Applications
- Household silicone articles: Silicone bakeware, baby pacifiers, food-grade silicone molds
- Silicone mold material: Resin casting molds, soap molds, candle molds, craft art molds
- Electronic industry: Thermal conductive silicone gel, electronic potting glue, insulation silicone sealant
- Coating & textile: Silicone release coating, textile soft silicone coating, screen printing silicone ink
- Medical silicone supplies: Medical silicone tubes, protective silicone parts, disposable medical accessories
- Industrial silicone processing: Liquid silicone injection molding, silicone extrusion strips/tubes, silicone adhesive sealants
Usage Instructions
Add the silicone inhibitor into vinyl silicone base material proportionally, stir uniformly at room temperature, then mix with platinum catalyst and hydrogen silicone oil before molding. Higher dosage leads to longer working time and needs higher curing temperature or longer heating time for full vulcanization.
Package & Storage
Standard package: 1kg / 5kg / 20kg plastic drum. Keep sealed, store in cool, dry and ventilated warehouse, avoid direct sunlight and high temperature environment. Keep away from strong oxidants.
- Hi, Winstar Silicone company, we are interested in your product silicone color masterbatch, could you please offer some free samples to us？ Our company address: ***LA,USA
- Hello Winstar, our product is compression molding product,could you advise which peroxide curing agent to use ?
- Hi friend, we have some problem in silicone to PVC bonding, that bonding strength is not well at all, how to improve it please ?
