PG-CORK Granule
the world's first patented material
What is PG-CORK Granule
PG-CORK Granule is a product that is an uniquely surface-treated cork chip using SORKIE’s patented technology to make cork suitable as a building material.
Cork granule processed in this way is most ideal for use as a building material because of enhanced workability and durability. Raw cork granule is not feasible for use on the jobsite as a building material especially for outdoor flooring.
SORKIE's PG-CORK Granule Development
High quality PG-CORK Granule has overcome the limits of natural cork for use as a building material. It offers a new way of producing various cork building materials while fully retaining the versatile and functional properties of cork.
In addition to its use as a building material, independent artists or DIY enthusiasts can easily create sculptures of artistic value or eco-friendly furnishings and small household items.

How to use
PG-CORK Granule is used by mixing with PU-based binders.
• Mix a 10:1 ratio of PG-CORK granule and PG-PU binder
- 10Liter Cork : 1kg Binder
- Mixing to the exact proportion is essential for a successful surfacing work
• Put the PG-CORK granule into the mixing container first and pour the PG-PU binder
• Mix well for 2-3 minutes until the material has no dry PG-CORK granules or clump (the mixture should be consistent in its texture)
• Use the mixture within 30 minutes

Description:
PG-PU Binder for PG-CORK Granule is a special eco-friendly polyurethane binder which includes more than 97% of solid contents.
It is a solvent-free binder that removes heavy metals and harmful solvents that exist in general polyurethane binder and doesn’t contain endocrine-disrupting chemicals (EDC), PAHs, T-VOCs, and heavy metals as well. It has better adhesive strength than general binders.
PG-PU Binder is a best product which has maximized natural material’s strength and improved durability by studying the world leading chemical company.
Eco-friendly, non-toxic binder
• Appearance: Transparent viscous liquid
• Solid contents (%): 98.5-99.9
• Density: 1.05 ± 0.1
• Viscosity (cps/25°C): 2,000-8,000
• Curing time: Summer 12H/Winter 24H
• Smell: Odorless(Similar with vegetable oil)
• Strength: 50% improved than the existing binder
Test result of heavymetal detection
• Heavy metal (Pb,Cd,HG,Cr6+)
• T-VOCs(Benzene)
• T-VOCs(Toluene)
• T-VOCs(Ethylbenzene)
• T-VOCs(Xylene)
• PAHs(Total amount)
• PAHs (Benzo[a]pyrene)

Advantages
• Excellent heat resistance and weather resistance
• Little change in physical properties within low & high temperature
• Excellent adhesive strength and high elasticity
• Does not contain organic solvent to protect worker’s health and eliminate environmental hazards
• Excellent storage stability
• It is possible work in 5-40C of outside temperature and 40-70% of relative humidity, and the final physical properties are manifested to about 8-11 hours after installation
• Since its solid content is more than 97%, it is more efficient than other companies’ binder which has a solid content of 93%
• It has a long life span by improving UV protective function
Installation Process
The installation method and sequence of PG-CORK granule is almost the same as that of EPDM rubber granule. PG-CORK Granule is lighter than SBR or EPDM granule, so workability is better (approx. 1/5 of the weight of EPDM rubber granule).
STEP 1: Preparation
STEP 2:
Application of Primer
STEP 3: Mixing
STEP 4:
Application of Cork
STEP 5: Curing
Clean the surface.
Remove all debris and dry the surface completely.
Make a primer by mixing PG-PU Binder and pure acetone in a ratio of 1:2.
First, apply this mixture (primer) to all edges of border using brush.
Apply the primer to the rest of cleaned surface with a paint roller.
Mix a 10:1 ratio of PG-CORK granule and PG-PU binder.
It is very important to use the proper ratio of PG-CORK granule and Binder.
Pour PG-CORK granules mixed with binder on the primed floor.
Spread out wide and flatten them with a push stick.
Use a roller or trowel to achieve the designed thickness and level.
* It is recommended to use a roller with a heavier weight than the roller for rubber.
Allow 24 to 48 hrs for curing, depending on the weather after the work is completed.
