KTR400 Siliconized Interior Acrylic Latex Sealant Product description KTR400 is a pure acrylic latex sealant formulated to provide a fast-setting pliable seal with minimal shrinkage. Features and Benefits KTR400 is an easy gunning, non-staining, general purpose sealant formulated from the highest quality acrylic polymer to offer exceptional flexibility and workability for any commercial construction acrylic sealant application. It can be used indoors or outside, and is tack-free in 15 minutes and ready to paint in 30-45 minutes with latexes or oil-based ***** also has been tested for acoustical properties to reduce sound transmissions when constructing partition partition walls. Basic Uses KTR400 can be used for general purpose interior and exterior caulking and as a back bedding glazing compound. It is also highly recommended as an acoustical seal in the construction of interior walls, ceiling and floors. It is also suitable for use on vinyl, aluminmum and wood siding as well as on bathroom and fixtures. Colors White, Limestone, Black, Cream, Almond Cream, Eggshell cream, Cedar, Beige Gray, Mortar, and Lava. Packaging 280ml, 10.1oz(300ml) / 310ml cartridges Bulk by drum: 200lt Coverage Rate 35 linear feet of joint per 10.1oz (300ml)cartridge for a 1/4”x 1/4” joint. For specific coverage rates that include joint size, and usage efficiencies. Applicable Standards KTR400meets or exceeds the requirements of the following specifications: ●STM C-834, Type OP, Grade- 18℃ ●AN/CGSB 19-GP-17M Joint backing Closed cell or reticulated polyethylene backer rod is recommended as joint backing to control sealant depth and to ensure intimate contact of sealant with joint walls when tooling.Where depth of joint will prevent the use of backer rod, an adhesive backed polyethylene tape (bond breaker tape) should be used to prevent three-sided adhesion.All backing should be dry at time of sealant application.

The depth of sealant may be equal to the width of joints that are less than 1/2” Wide. For joints ranging from 1/2”to 1”(13mm to 25mm)wide, the sealant depth should Be approximately one-half on the joint width. The maximum depth of any sealant application should 1/2”(13mm). WINDOWS PERIMETERS – For fillet beads, or angle beads around windows and doors, The sealnat should exhibit a minimum surface contact area (C) of 1/4”onto each Substrate. Surface preparations Surfaces must be sound , clean, and dry.All release agents, existing waterproofing, Dust, loose mortar, laitance, paints, or other finishes must be ***** can be Accomplished with a thorough wire brushing, grinding, sandblasting, or solvent washing, depending on the contamination. KTR400 recommends that surface temperatures be 40℉（5℃）or above at the time the sealant is applied. If sealant must be applied in temperatures below 40℉. Priming KTR400 adheres to common construction substrates without primers;however, KTR400 always recommends that a mock-up or field adhesion test on the actual materials being used on the job be conducted to verify adhesion. The field adhesion test can be found in appendixes X1 of ASTM C 1193, Standard Guide for Use of Joint Sealants. Application Apply KTR400 with conventional caulking equipment filling the joint from the bottom ***** tool the sealant with a spatula to ensure intimate contact with the joint walls.Dry tooling is always preferred, although water can be used in limited amounts to slick the spatuta if ***** window and door perimeter fillet bead applications, a 1/4” minimum surface area is recommended. Dry Time At 72℉(22℃), 50% R.H., KTR400 is tack free in 15 minutes and drieds at a rate of about 1/8” per day but can be painted after only 30 to 45 minutes with latexes, or oil-based paint.As the temperatures decrease, the dry time of KTR400 will increase.A good rule of thumb is one additional day for every 10℉ decrease in temperature. Clean up Excess sealant and smears along the joint interface can be cleaned up or removed with soapy water before the sealsant skins.Any utensils used for tooling can also be cleaned with woapy water. Limitations Do not apply KTR400 to damp or contaminated surfaces. Always utilize the accompanying MSDS for information on Personal Protective Equipment (PPE), and health hazards. Warranty KTR400 warrants its sealants to be free of defects in materials, but makes no warranty as to appearance or color.Since methods of application and on-site conditions are beyond our control and can affect performance, KTR400 makes no other warranty, expressed or implied including warranties of MERCHANTABILITY and FITNESS FOR A PARTICULAR PURPOSE, withrespect to KTR sealants. KTR’S sole obligation shall be, at its option, to replace, or refund the purchase of the quantity of KTR sealant proven to be defective and KTR400 shall not be liable for any loss or damage.
