产品特点：
环保健康，不含异氰酸酯类和有机锡化合物。高强度，粘结力强;固化快，脱粘速度快，固化后表□　面不发粘;
对潮湿表面具有良好的粘接力;
具有优异的抗紫外性能、耐老化性能和耐湿气性能。

应用领域：
1、在建筑和工业装配领域中作为高强度弹性粘合剂使用;
2、可广泛应用于卫浴五金安装、镜面相框安装、强韧粘合封固玻璃、镜子、木材、塑料、水泥和各种金属的粘接;
3、在建筑应用领域，电视背景墙，墙板安装;
4、可用于快速粘接面板，绝缘板，装饰板和壁脚板等。

使用方法：
1、使用环境>7°C;粘ㄨ接面保持清洁，避免灰尘和油脂;小型挂件即粘即◥撤压，承重型件加压10-30分钟(温度20C，湿度50%)，即可撤压。另外，刚涂抹的粘胶可用丙酮清洗。
2、使用注意事项:因胶体为潮固化，用喷雾湿∩润干燥空气，或用湿水海绵涂抹被粘物表面，粘接物内部或者表面的水分以及空气中的湿度有助于固化粘合。

储存：在保持原包装密封条件下，建议储存在阴凉(低于25°C )和干燥处。

687special adhesive for rock plate
687 reactive fast curing polyurethane adhesive has good adhesion to many materials.

It can be used to bond and seal almost all surfaces and base materials. It is an ideal general-purpose sealant and adhesive productfor construction and industry. It has excellent crosslinking curing speed, especially suitable for high-strength bondingand
sealing occasions.

Product characteristics:
Environmentally friendly and healthy, free of isocyanate and organotin compounds. High strength, strong adhesion, fast curing, fast debonding speed, no adhesion after curing;
It has good adhesion to wet surface.
It has excellent UV resistance, aging resistance and moisture resistance.

Areas of application:

Used as a high strength elastic adhesive in the field of construction and industrial assembly;
It can be widely used in bathroom hardware installation, mirror photo frame installation, strong and tough adhesive sealing glass, mirror, wood, plastic, cement and all kinds of metal bonding.
In the field of architectural application, TV background wall, wallboard installation;
It can be used for fast bonding panel, insulation board, decorative board and wallboard, etc.

Methods of use:
The working environment is more than 7 °C; the adhesive surface is kept clean to avoid dust and grease; the small pendant is pressed immediately, and the heavy duty part is pressurized for 10-30 minutes (temperature 20C, humidity 50%). In addition, the newly smeared glue can be cleaned with acetone.

Points for attention: because the colloid is moisture solidified, spray wet dry air, or smear the adhesive surface with wet water sponge, the moisture inside or surface of the adhesive and the humidity in the air help to solidify the adhesive.

Storage:Under the condition of keeping the original package sealed, it is recommended to store it in a cool (less than 25 °C) and dry place.

Technical parameters：
Watch dry time: 10 minutes
Complete curing time: 3-12 hours
Gravity per square centimeter after complete curing: 50KG shelf life: 8 months
Product implementation Standard: JC/T2186--2013
