HY-638 Silicon Material for Gypsum Products
Usage:
For toy gifts and craftwork gift, products with complex fine details, and made in pouring way.
HY-638 Silicon Material for Gypsum Description:
HY-638 Silicon Material for Gypsum is mainly used for toy gifts
and craftwork gifts with the advantages of good tensile strength, high tear
strength, high temperature resistance, high duplication times and repeated use,
etc. It is suitable for small products or fine and precision products which is
difficult to demould. This plaster molding silicon is one of the products with
the highest use level in the production of craftwork gifts and the shrinkage is
up to 2‰.
HY-638 Silicon Material for Gypsum Applications: Poly technique, lightings, candles,
and molds in multiple pieces for large products.\
HY-638 Silicon Material for Gypsum Datasheet:
Model | Appearance | Viscosity (cps) | Hardness (Ao) | Tensile Strength (Mpa) | Tear Strength (KN/m) | Elongation (%) | Mixing ratio(%) | Operating Time(H) | Curing Time(H) |
638 | White | ≤38000 | 36±2 | ≥3.8 | ≥28 | ≥360 | 2~3 | 0.5~1 | 2~5 |
HY-638 Silicon Material for Gypsum General Description:
HY-638 Silicon Material for Gypsum are
general called two-component room temperature vulcanization silicone rubber with
excellent fluidity and good operational performance. Add curing agent of 2%-3%
at the room temperature, the plaster molding silicon is still operational within
30 minutes,and in 2-5 hours, an elastic silicon mold will be obtained with
resistance to deformation, high-temperature, acid and alkali and expansion. The
plaster molding silicon is mainly applicable to mold duplication of poly crafts,
resin craftworks, lightings, candles, etc. and fabrication of precision
molds.
Operation Instruction for HY-638 Silicon Material for Gypsum
The product is white or red flowing liquid with general hardness
of 34—38A°after curing . If the customer wants to make large products and large
size molds, the mold should be made of silicone rubber with high hardness. On
the contrary, if the mold with fine and precision patterns , it should be made
of silicon with low hardness. The amount of the curing agent depends on the
actual requirements of the customer. If molds requiring fast drying and demould,
more curing agent is needed; contrarily, if molds requiring slower drying and
demould, less curing agent is needed.
(Note: our company does not recommend you to add silicone oil. If
a special soft silicon mold or fine detailed and complex patterns products are
required, 5%-10% silicone oil can be added to soften the mold for easy
demould.)
The proportions and reactions of the curing agent and the
HY-638 Silicon Material for Gypsum are listed as follows:
1. Adding curing agent 1%, the silicone can still be operated
within 2.5 hours and can be demoulded after 6-8 hours.
2. Adding curing agent 2%, the silicone can still be operated
within 50 minutes to 1 hour and can be demoulded after 2-3 hours.
3. Adding curing agent 3%, the silicone can still be
operated within 28 - 30 minutes and can be demoulded after 1.5-2 hours.
4. Adding curing agent 4%, the silicone can still be
operated within 10 - 15 minutes and can be demoulded after 1 -1.5 hours.
