RTV-2 silicone rubber make molds for gypsum products.

RTV-2 silicone rubber with 30-35 shore A can make molds for gypsum products.many people make molds by RTV-2 addition silicone rubber with 30-35 shore A.

addition silicone rubber with platinum catalyst,the linear shrinkage will better than condensation silicone rubber.

But it expensive than condensation silicone rubber.

About $8.00-10.00/kg

what is RTV silicone rubber?two compound silicone rubber with catalyst

Description:

RTV Silicone rubber(room temperature vulcanization silicone rubber) is a type of silicone rubber made from a two-component system (base plus curative; A+B) available in a hardness range of very soft to medium - usually from 0 shore A to 70 Shore. RTV silicone rubber can be cured with a catalyst consisting of either platinum or a tin compound such as dibutyltin dilaurate Applications include low-temperature overmolding, making molds for reproducing, and lens applications for some optically clear grades.

Application:

To produce the material, the silicone rubber is mixed with the catalyst or curing agent. Usually the mixing ratio is few percent. In order for the RTV silicone rubber to reproduce the surface texture, attention is paid to the cleanliness of the original. Vacuum deairing removes entrained air bubbles from the mixed silicone and catalyst to ensure optimal tensile strength,which affects reproduction times. In casting and mold making, RTV silicone rubber reproduces fine details and is suitable for a variety of industrial and art related applications including prototypes,furniture,sculpture and architectural elements. RTV silicone rubber can be used to cast  materials including wax, gypsum,low melt alloys/metals and urethane,epoxy or polyester resins(without using a release agent). RTV silicone rubber industrial applications include aviation, aerospace, consumer electronics, and microelectronics. Some aviation and aerospace product applications are cockit instruments, engine electronic potting and engine gasketing.  RTV silicone rubber are used for their ability to withstand mechanical and thermal stress.

How to make molds by molding silicone rubber---tin catalyst/tin cured silicone rubber make silicone molds

silicone molds are the quick way to make molds.the process as follows:prepare original product,make frame and fixed it.then weighing and stir the silicone and catalyst.next pouring the silicone to every parts of mold after de-air by vacuum machine. Finally, remove the frame after silicone was cured completely,and trimming the mold.

Tools and materials:silicone and catalyst,plastic board,electronic scale,caps,sellotape,glass bar,releasing agent,scissor,knife,Hot melt glue guns and Spatter.

1)DISPOSE THE ORIGINAL PRODUCT

①deburred of the original product by knife,be careful not to damage the surface and parts.

②spray the releasing agent on original product,Pay attention to the deep hole or narrow slot.

2)MAKE FRAME

①Stick the frame by hot melt glue guns,to prevent the silicone outflow from the gap.

②To increase about 20-40mm according to the size of original product ,so that better for pour the silicone.

③Put and fix the original product into the middle of location of frame.

3)WEIGHING SILICONE AND CATALSYT

①weighing the part A and part B according to the ratio that supplied by the factory.

②Please be sure that mixing by weight ,not volume.

4)MIXING AND STIRRING

①mix the silicone and catalyst according to the weight.

②Be sure to Stir evenly,otherwise,will effect the time of duplication.

5)DE-AIR BY VACUUM MACHINE

①de-air by vacuum machine after stir evenly.

②The time about 10mins,because too long time will produce cross linking curing reaction.

6)POUR THE SILICONE TO FRAME

①pour the silicone after de-air.

②Pour the silicone over the original products,and pour more silicone about 20-50mm on the top of original products.

③Blowing bubbles by Spatter on the surface of silicone.

7)WAITING FOR CURING

①put the frame away ,and waiting for curing.

②The optimal temperature of curing about 20-30℃.

③can heat curing by the oven if the temperature below than 0℃.

8)TRIMMING THE MOLDS

①find the remarks and cut open the molds after curing.

②In order to prevent silicone molds will deformation,Please ensure that de-mould without affect by outside force .

③Trimming the silicone molds by scissor.

9)COMPLETE THE OPERATION

①all progress of make molds are complete after trimming.

②Suggestion:please use the silicone mold after 24hrs,to prevent deformation.

Food grade silicone putty,easy make molds for craft by hands

Silicone putty is a two-part RTV silicone rubber,non-toxic material with the viscosity of putty for making simple but detailed moulds.the mould will withstand temperatures up to 315°C.

This rubber does not require moulds or containers which liquid silicon or our RTV rubber requires. You simply mix equal parts of Part A was an equal quantity of Part B which requires less time and skill in preparing the rubber ready for application.

Simply put, it is the fastest, easiest means of producing a reusable mould that is flexible and accurate.

As the moulds can be safely used at oven temperatures they can be used for polymer clothes or for liquid resin jewellery castings using either polyester, epoxy or polyurethane resins. The special food safe resin can be used for chocolates, sweets for gelatin.
