Like many polyureas, urethanes or hybrids chemical reaction and fusion occurs to produce the cured coating.? Our SLPV Plural Component Lining consists of liquids (parts A & B- Resin/Binder) and solids (PART C- polyurea / polymer micropowder). ?High grade polyurea hybrid are excellent for bed liner with highest adhesion. Texture control is within the process between liquid and solid components; expansion at full cure plus emulsified (not fully melted) solids. ?The SPLV Line carries the only polyurea with controllable texture (hardness), profile (flat / slight orange peel / course), any UV color and purest clear. Less and more expansion equate to harder and softer textures (or more to less adhesion) respectively.
These materials, once fully cured, yield average 55% increase in its original volume.?
Example using materials in a standard 6? bed liner kit:
- Bed liner is mixed from 1:1 to 3:1 as solids: liquid.? For standard adhesion and thickness, use 1.5:1 as liquids to powders.
- .75 gallons of liquids mixed with 1.5 part solids will = 1.875 gallons * 1.23 (expansion) = 2.32 gallons fully cured
Other calculations for total volume of finished bed liner kit
Base coat + top coat to achieve thicker bed with greater adhesion –? In this example, a base coat comprised of 1:1 as solids to liquid for higher adhesion rate.? In conjunction, a second layer applied at 2:1 is used to achieve a thick top layer where adhesion is not as much of a concern between same materials (bed liner attached to bare metal versus 2nd layer of bed liner bonded to first layer of bed liner)
How expansion is calculated for 2 layer bed liner
- Liquids for layer 1 is .75 gallons/2 = .375 gallons
- Solids for layer 1 is .375 gallons of polymers
- Total for layer 1 = .75 * expansion rate of .18 = .885 gallons
- Liquids for layer 2 is .375 gallons
- Solids for layer 2 is .75 gallons
- Total for layer 2 = 1.125 * 1.25 (expansion) = 1.4 gallons
- Total Sprayable gallons = 2.29 gallons
