HY-E600 Addition Cure Mold Making Silicone Rubber

Description

HY-E600 is a kind of two part silicone rubber in addition cure or platinum cure　type with mixing ratio of 1:1 or 10:1 . It can cure at room temperature as well as under heat . It’s a kind of food grade silicone and mainly used for mold making.

Application

HY-E600 silicone rubber　is　mainly used　for　making molds of concrete stone,GRC,polyurethane　products ; wax, candle　decoration ; rapid prototyping and tyre molds; chocolate,candy and similar products .

Characteristics

＊An exceptional fluidity and good operability, easy to demold

＊Good　tensile and tear strength

＊Outstanding bubble releasing

＊Non-deformation

＊Low shrinkage

＊Aging resistance　,high temperature resistance (200℃)

＊Environmentally, food-grade

Operation instructions

Step 1: prepare the original molds

Prepare an perfect original mold and clean it totally before operation .

＊Notes:Make sure your original molds　and operation tool cleaned up totally to avoid uncure problem .

Step 2: Take 100 G part A and 100 G part B (Or 100 G part A and 10 G part B) and mix them evenly.

＊Notes: Addition cure mold　making silicon rubber is two part　flowing liquid , Pls follow the step strictly:

1.Weigh the two part exactly by electronic weight..

If any part not in exactly weight , it may cause changing of hardness , or even cause uncure problem.

2.Mix part A and part B evenly.

Otherwise the silicon rubber will be partly solidified and this will give birth to difficulties in your final operation. What’s more, the finished molds will meet a short life. All of these will cause a waste of silicon rubber.

Step 3: Vacuum pumping

Without exception, this step takes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available.

Step 4: Pouring casting or Brush operation

＊Notes:1. For simple pattern products we suggest use pouring operation way , which will be very easy to operate and demould. Pourable silicone require light viscosity which will be easy to flow smoothly and easy to de-air .

2.For delicate pattern products we suggest use brushing operation way , which can copy the pattern exactly . Brushable silicone require high viscosity which won’t be easy to flow away and easy to brush .

3. We suggest to set the silicone mold for another 12 hours after demould before put into large production .

Warm tips :

As addition cure silicone is a kind of platinum cure system ,which will be easy to cause uncure problem ,so

Kindly follow the tips below :

＊Do not mix with liquid condensation silicone rubber or even the tool which used for condensation silicone

＊Do not mix with organic matter which contains N, S, P organics and ionic compound like Sn, As,Hg, Ph,

＊Do not add any pigment or powder into the addition cure silicone rubber without any testing to prevent uncure problem

模具硅胶不加固化剂能自然凝固吗?
模具硅胶不加固化剂能自然凝固吗?我的固化剂没有搅拌均匀，所以造成了模具部分已经固化，同时有些地方还很软，请问这些软的地方以后会逐渐固化吗?依据红叶模具硅胶厂的经验，模具硅胶加了硬化剂以后必须搅拌均匀，如果没有搅拌均匀，就会发生部分不固话现象。如果没有固话的地方48小时以后还不能固话的话，这块模具就宣告报废了，就不会固化了，只能把它清理干净后重新制作模具。我的固化剂没有搅拌均匀，所以造成了模具部分已
加成型硅胶的操作方法
1、准备好容器及搅拌机或搅拌棒, 例：用两个相同容量的器具，将A组分和B组分两种组分分别用容器按等量的方式量好，然后将A/B两个胶倒到同一个大容器中搅拌均匀，模具硅胶外观是流动的液体，A组份是带固化成分的硅胶，B组份是硅胶。(注:A/B两组份一定要搅拌均匀，如果没有搅拌均匀，模具会出现一块已经固化，一块没有固化，甚至造成模具报废状况）。 2、较好能将搅拌好的硅胶用抽真空机进行抽真空,(如不抽真空
人体硅胶使用方法
人体硅胶产品使用方法：将模具清洗干净，吹干，不能留有水迹，将A、B组份按重量比1:1混合均匀，经真空机脱泡后，灌在模具里面，操作时间视温度而定30分钟左右，固化时间(室温)2-3小时，加温80°C-100°C可在数十分钟内固化。比例误差控制在0.05之内。包装： A组份20kg，B组份20kg装。按非危险品运输，贮存期半年，密闭、防酸碱及杂质。
模具硅胶耐用的细节点
细节一：硅胶和固化剂要搅拌均匀否则会出现表干里不干，或者固化不均匀的情况，出现这种情况会造成模具的报废，要尽力避免。细节二：抽真空排气泡很多人认为常温固化的模具硅胶是不需要抽真空的，在不抽真空的情况下你做的模具里面可能会存在一定气泡，模具里面都有气泡这个模具抗撕裂还能好吗？细节三：根据产品选择操作工艺一般小产品选择倒模操作工艺偏多，但是如果这个产品尺寸很大，一定要用刷模，虽然灌模省工省时省力，但是
