How to use low-viscosity LSR silicone material silk screen Silicone
heat transfer (Positive transfer) method
Silicone heat transfer (Positive transfer) method
Step one ---.Material:
1) Silicone RH625-45Z A, curing agent RH625-25Z B, color paste.
2)Silicone heat transfer coating: RH625-25M A/B.
3) Hot melt adhesive
4) High temperature separation sheet, positioning paper
Step two----Process:
1) RH6250-45M A/B evenly coated fabric surface, 3-5 times. Make
sure that the surface is dry before each coating and processed at
high temperatures.
2) Bake dry each time, do not stick to the plate is advisable.
3)Transfer RH6250-25Z A/B printing glue products 100:10 evenly,
printed on the surface of hot Silicone glue, printed three times
the best, each time to dry the table is appropriate.Stay with the
silicone.
4) Silicone RH6250-25Z A/B according to 100:10 deployment, evenly,
press 8-10% add color paste, evenly, silk screen on the transfer
glue, silk screen printing once, baked to the table dry, until the
desired effect and thickness, color.
5)Bake at 140 degrees for 30 minutes.
6) Press 150 degrees for 15 seconds.According to the fabric
thickness and silicone thickness to increase the pressing time.
3.Notes:
1) A. B is sealed separately and stored at room temperature for 3
months
2)Each item is the result of repeated tests, please be sure to
follow the operation steps.
Description
Features:

Processing
Mixing
Rui-he RH 6250 series Liquid Silicone Rubber is a two-component
material supplied as parts A and B,
which should be combined in a 1:1 ratio. Meter mix equipment which
pumps, meters, and mixes
the two components without the incorporation of air is strongly
recommended for production.
Pot Life
After the A and B components are mixed, Liquid Silicone Rubber will remain usable for at least 48 hours at room
temperature.
Storage
The 'Best use before end' date of each batch is shown on the
product label.
Storage beyond the date specified on the label does not necessarily
mean that the product is no longer usable.
In this case however, the properties required for the intended use
must be checked for quality assurance reasons.
